Atlanta remains the world's busiest airport

Atlanta’s Hartsfield-Jackson (ATL), the hub of Delta Air Lines, remains the world’s busiest for passenger traffic, according to new preliminary figures from Airports Council International (ACI). It takes the title of the world's busiest as the city is within a two-hour flight of 80% of the United States population of more than 300 million people.

The rankings were revealed today by ACI, including both domestic and international arrivals and departures.

The US hub welcomed just under 104 million passengers in 2017, down 0.3% on the previous year.

The top three busiest airports are unchanged from 2016, with Beijing in second place and Dubai in third, while Tokyo Haneda displaced Los Angeles International from the fourth sport. London's Heathrow remains the busiest airport in Europe with 78million passengers (up 3%).

In the rest of the top 20, Delhi jumped from 22nd to 16th for 2017, solidifying its status as one of the fastest-growing airports in the world for passenger traffic. Guangzhou in China grew by 10.3% making it the second fastest growing airport among the top 20.
